It would have to be full automation, not the current system were the car drives along merrily & then when it discovers a problem it can't handle it hands control back to the driver.
I saw an advert for Wayve & they expect the driver to sit like this alert & ready to take control at a moments notice. You can't get drivers to be that alert now when they are in sole control of the vehicle, it is an impossible task to expect someone to sit there for a journey & not get their phone out or stick a movie on the central control screen (for the passengers obviously)
